Well, I have already confessed my skepticism - however, its really hard to say.  One thing in their favor, they appear to be using a centrifugal pump with a scroll diffuser very similar to that on a turbo charger.  Meaning that if indeed they can spin it fast enough it should work.  Now one of the individuals on their  forum indicated they measured its spin at 25000 rpm.  That's a bit slow for a turbocharger but, it may indeed be enough to produce some boost. 
 
We all know that motors and electric devices have made some major improvements in the last decade or so, but still a 1 1/2 HP electric motor just seems a bit on the large size physically and what really bothers me is no specifications on their web site.  Hard to assess and/or refute data you don't have {:>).
 
But, what really bothers me is I just don't see how you could even manufacture the scroll housing and compressor blades much less a 1 - 1 1/2HP electric motor and sell it for $99.00 - even if made in China.  I really want to believe - but, its sure is hard to find any data to help that belief along {:>).
 
I guess IF I really thought it was credible, I would have my $99.00 check in the mail and I don't.

Ed, this thread is starting to look like the electric water pump thread that can't work.  I just have a feeling that your inquisitive mind is going to go somewhere with this one.  JohnD
